Abstract: A control apparatus according to an aspect of the present technology includes a signal generation section. The signal generation section generates speckle data on the basis of an image signal of a subject imaged by using laser light as illumination, and generates a control signal for controlling output from a laser light source that emits the laser light on the basis of the generated speckle data.

Abstract: To provide an image analyzing technology capable of obtaining an image with less shading and with enough speckle contrast. An imaging apparatus includes: a light source that irradiates an imaging object with coherent light with a first irradiation condition and a second irradiation condition; a speckle imaging unit that captures a first speckle image obtained from scattered light of the imaging object irradiate at the first irradiation condition, and a second speckle image obtained from scattered light of the imaging object irradiate at the second irradiation condition; and an information processing unit that separates speckle images at boundaries of average luminance difference formed in the first speckle image and the second speckle image, connecting the separaged speckle images at the boundaries, and analyzes the combined speckle combined image.
